Problems solved by technology

The existing seedling raising method of peony for oil mainly adopts the traditional paeonol seedling raising method, but the paeonol seedling raising method uses multiple technical means such as growth promoters, rooting powder, and various chemical fertilizers in order to ensure the paeonol output during the seedling cultivation period To promote the development of its roots, this method is likely to cause a very low seed setting rate of peony seeds; although the steps of adding hormones and fertilizers to promote root growth are eliminated when growing seedlings of peony with oil, it is likely to cause insufficient nutrition for seedling growth during seedling cultivation. The growth is slow, and the effect of improving the seed setting rate is not obvious. The breeding mode of this method is simple and extensive, the seed germination time is long, and the emergence rate is not high, only 65%~80%

Embodiment 1

[0104] At the beginning of June 2011, sandy loam soil, which is deep and fertile, easy to drain and retain moisture, was selected as the soil for the nursery. It was measured that the physical clay content of the soil was less than 13%, and the physical sand content was higher than 58%. The pH of the soil should be between 7.5 and 8.2. Apply 10 to 20 kg of gypsum, 1 to 3 kg of potassium dihydrogen phosphate and 100 to 150 kg of farmyard manure that does not contain pig manure; One or any combination of cow dung, decomposed chicken manure, decomposed straw or decomposed domestic waste.

[0105] For nurseries with many weeds, use 600g of 10% glyphosate and 40g of washing powder and add 30kg of water to make liquid A and spray it. After the weeds are dead, choose sunny days to manually deep plow the land with weeds , The land after deep plowing continued to be exposed to the sun until early August.

Embodiment 2

[0116] In mid-June 2011, sandy loam soil, which is deep and fertile, easy to drain and retain moisture, was selected as the soil for the nursery. It was measured that the physical clay content of the soil was less than 13%, and the physical sand content was higher than 58%. The pH of the soil is between 6.5 and 7.5.

[0117] For the plots with many weeds in the nursery, use 680g of 10% glyphosate and 53g of washing powder plus 35kg of water to make liquid A and spray it. After the weeds die, choose sunny days to manually deep plow the land with weeds. The land after deep plowing continued to be exposed to the sun until mid-August.

[0118] In mid-August, choose a sunny day for deep plowing and plowing of the nursery. The plowing depth is 25cm. One week before plowing, apply 860kg of farmyard manure without pig manure and 105kg of cake fertilizer to each acre of nursery, and then apply dihydrogen phosphate 26kg of potassium and 13kg of diammonium phosphate, 13kg of phoxim gran...

Embodiment 3

[0128] In late June 2011, sandy loam soil, which is deep and fertile, easy to drain and retain moisture, was selected as the soil for the nursery. It was measured that the physical clay content of the soil was less than 13%, and the physical sand content was higher than 58%. When the measured soil pH is 5.5-6.5, apply 20-30 kg of plant ash and 150-200 kg of farmyard manure that does not contain pig manure per mu of nursery land. The farm manure is one of decomposed human manure, decomposed cow dung, decomposed chicken manure, decomposed straw or decomposed domestic garbage, or any combination thereof.

[0129] For the plots with many weeds in the nursery, use 800g of 10% glyphosate and 60g of washing powder and add 40kg of water to make liquid A and spray it. After the weeds are dead, choose a sunny day to manually deep plow the land with weeds , The land after deep plowing continued to be exposed to the sun until late August.

[0130] In late August, choose sunny days for de...

Abstract

The invention relates to a method for cultivating seedlings of oil peonies, and belongs to the field of agricultural seedling cultivation. The method comprises the following steps: selecting a nursery; performing weeding in advance; performing deep ploughing and tedding; performing soil preparation and making furrow ridges; harvesting seeds; processing the harvested seeds; sorting the processed seeds; processing the sorted seeds before cultivation; sowing the processed seeds; managing seedlings; managing nursery stocks. The characteristics of soil are changed by the method of combining farm manure with a chemical fertilizer. The seeds for sowing are harvested at the best harvesting time; the seeds to be cultivated are processed by gibberellin, ethyl alcohol, sodium p(dimethylamino) benzenediazo sulfonate solution, carbendazim and plant ash, and a culture solution is generated during the cultivation of onions, so that the seed dormancy is broken, the germinating time is advanced, and the germination rate is increased. Diseases are prevented during cultivation, and different medicaments are sprayed in different seasons so as to prevent diseases, so that the seedling survival percent is increased. After being cultivated by the method disclosed by the invention, the nursery stocks are thick in plants, the seedling survival percent is high, the quality is greatly improved, after the nursery stocks are planted, the seed setting rate is high, and the nursery stocks cultivated by the method disclosed by the invention are good varieties for the oil peonies.

Description

technical field [0001] The invention relates to a method for raising seedlings, in particular to a method for raising seedlings of Fengdan for oil. Background technique [0002] Peony for oil is a shrub plant. Distributed in Heze in Shandong Province, Luoyang in Henan Province, Taibai Mountain in Shaanxi Province, Fuping in Shaanxi Province, Bozhou City in Anhui Province, Fenghuang Mountain in Tongling City, Gansu Province and Xiangxi in Hunan Province. There are only two varieties of peonies for oil used in commercial production: Fengdan and Ziban. [0003] Peony for oil is a new kind of woody oil crop, which has the outstanding characteristics of "three highs and one low": high output (the yield per mu can reach 300 kg in five years, and the comprehensive benefit per mu can reach 10,000 yuan), high oil content (seed oil content 22%), high quality (unsaturated fatty acid content 92%), low cost (peony for oil is drought and barren resistant, suitable for afforestation and ...
